Bug#344366: kernel-image-2.6.8-2-686: Samsung SFD-321U/EP detects as 8 LUNs
Package: kernel-image-2.6.8-2-686
Version: 2.6.8-16
Severity: normal
Tags: patch
Hello kernel team,
I have a problem with my USB Floppy Drive -- it detects as eight
separate LUNs and none of them function properly :( I did some
searching and it seems that someone at SuSe ran into, and fixed this
problem already in their kernel-source-2.6.13-15.7 package.
Following this is an excerpt from my boot messages showing the problem,
and attached is the patch included by Suse in their new kernel (released
at the beginning of the month). I would appreciate it if you could
included it in future debian kernels and forward it upstream.
Thanks,
--Joe
